JAMES J'. CONNORS, 0F JUNEAU, TERRITORY OF ALASKA.

HEATER.

To all whom it may concern:

Be it known that I, James J. CoNNoRs, a citizen of the United States,residing at Juneau, in the Territory of Alaska, have invented new anduseful Improvements in Heaters, of which the following is aspecification.

This invention contemplates the provision of a gasoline heater andvaporizer, designed for association with the intake manifold of anengine. and arranged to heat and vaporize the gasoline just prior to itsadmittance into the firing chamber to facilitate starting of the motorin cold weather.

The invention contemplates the provision of a device of this characterwhich is very simple in construction, and designed to permit of itsassociation with the intake manifold of any construction.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application. like numerals ofreference indicate similar parts in the several views, and wherein:

Figure 1 is a view of an intake manifold showing the location of theheater and vaporizer thereon.

Figure 2 is an enlarged longitudinal sectional view through. the deviceforming the subject matter of the present invention.

Figure 3 is a top plan view.

Figure 4 is a detail view of the bushing showing the electrode andheating element associated therewith.

Figure 5 is a view in elevation of the complete device.

Figure 6 is a bottom plan view.

The combined heater and vaporizer forming the subject matter of thepresent inven tion comprises a shell 10 which is smooth for a portion ofits length as at 11. and threaded for the remaining portion of itslength as at 12. The smooth portion is provided with perforations 13 andthis portion is adapted to be arranged in the intake manifold projectingtherein through an opening formed in the manifold for this Applicationfiled March 10, 1923.

purpose. It is of course to be understood. that the shell is threaded inthis opening by means of the threads 12. Threaded into the shell is abushing 13 which is provided with a core 14 of mica or other insulatedmaterial, the core being spaced from the shell as shown. Passed throughthe bushing and core is an electrode 1 1, one end of which is attachedto the adjacent end of a heating coil which surrounds the core andspaced between the latter and the perforations of the shell. A nut 15 isthreaded on the inner end of the electrode and is utilized for holdingthe heating element 16 associated therewith. The opposite end of theheating element bears against the bushing. The electrode is energized bya suitable wire 17 leading from the battery or other source of currentfor the spark plug for the motor, and is controlled by a suitableswitch. not shown, arranged within convenient reach of the operator ofthe vehicle.

In practice, when the device is used, the gasoline as it passes theperforated portion of the shell and brought in contact with the heater,is heated and vaporized just prior 7 to its admittance to the combustionchamber which of course materially facilitates starting of the motorespecially in cold Weather, and is particularly useful in saving thebattery, which is subjected to great strain and wear during cold weatherwhen called upon and used during the starting of the motor. the deviceis very simple in construction and can be manufactured and sold at anominal cost and furthermore it can be usel in conjunction with any typeof manifol While it is believed from the foregoing description, thenature and advantages of the invention will be readily apparent, Idesire to have it understood that I do not limit myself to what isherein shown and described and that such changes may be resorted to whendesired as fall within the scope of what is claimed.

Having thus described the invention, 1 claim:

A gasoline heater and vaporizer for intake manifolds comprising a shellhaving a smooth portion and a threaded portion, and adapted to bethreaded into an opening in said manifold, a core of insulating materialarranged within the shell and spaced therefrom, an annular shoulderarranged centrally of the core, and an electrode passed longitudinallythrough the :core, a; heating wire having one end looped about the coreand reposingupon said shoulder, said-heating element beingwoundabout-thecore bee neath said shoulder and having its other end secured to saidelectrode, a bushing threaded into said shell and impinging the loopedend of saidheating element against JAMES J. CONNORS.
